Removable back rest

Abstract

A removable backrest is attached to a cooler in such a manner that does not interfere with the opening or closing of the lid nor does it interfere with the sealing mechanism of the cooler. The removable backrest inserts into existing slots positioned in the walls of certain commercially available coolers. The angle of the frame permits a user to sit on the complete lid of the cooler and lean against the backrest. While the backrest is in position, the lid may be opened or closed at the user's convenience.
